This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To investigate the effects of remifentanil and dexmedetomidine controlled hypotension on coagulation function,cerebral oxygen metabolism and amino acid neurotransmitter levels in elderly patients undergoing orthopedic surgery.Methods The elderly patients who underwent lower extremity orthopedic surgery were divided into group A(given dexmedetomidine for hypotension),group B(given remifentanil for hypotension)and group C(given remifentanil combined with dexmedetomidine for hypotension)according to different anesthetic drugs.Systolic blood pressure(SBP),diastolic blood pressure(DBP)and heart rate(HR)were compared among the 3 groups.Cerebral oxygen metabolism[arterial oxygen content,(CaO2),oxygen saturation of internal jugular vein(SjvO2),oxygen content of internal jugular vein(CjvO2)],coagulation function[activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),plasma fibrinogen(FIB)],amino acid neurotransmitters[glutamic acid(Glu),aspartate(Asp),gamma-aminobutyric acid(GABA)]were compared,and the occurrence of adverse drug reactions during the trial were compared.Results At 12 h after anesthesia,the APTT of group A,group B and group C were(17.26±2.77),(17.37±2.92)and(31.11±4.74)s,respectively.GABA were(18.74±2.71),(19.22±2.60)and(23.37±2.59)mmol·L-1,respectively.3 min after withdrawal,CaO2 in group A,group B and group C were(139.31±9.03),(140.90±8.70)and(131.75±10.11)mL·L-1,respectively;SjvO2 were(63.59±2.23)％,(63.40±2.44)％and(68.82±3.36)％,respectively.The above indexes of group C were compared with those of group A and group B,and the differences were statistically significant(all P＜0.05).The incidence of adverse drug reactions in group A,B and C were 12.82％,27.50％and 7.32％,respectively.The incidence of adverse drug reactions in group C were lower than that in group A and group B(P＜0.05).Conclusion Remifentanil combined with dexmedetomidine for controlled hypotension in elderly orthopedic surgery has better blood pressure control effect,can improve postoperative coagulation function,maintain cerebral oxygen metabolism balance,reduce cognitive function injury and anesthesia adverse drug reactions.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Platelets are reprogrammed by cancer via a process called education, which favors cancer development. The transcriptional profile of tumor-educated platelets (TEPs) is skewed and therefore practicable for cancer detection. This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n = 3; Netherlands, n = 5; Poland, n = 1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, and early-stage ovarian cancer. However, these observations warrant prospective validations in a larger population before clinical utilities.
